Replace props with data for global_toggle
What does this MR do and why?
This MR makes isLoading and disabled props of global_toggle a part of the state, instead of props
Props are immutable by default, however (and this is intended) we're mutating these outside - https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/protected_branches/protected_branch_edit.js#L36 - so these could not be props
Additionally this trigger error about props mutation in Vue.js 3
